Upgrading from 8.1.7 to Oracle 10g R2 on Unix

We have Oracle 8.1.7 installed on Tru64 Unix, and we are planning to upgrade the operating system to new servers with HP Itanium Unix and Oracle 10g R2. Could you provide us with your view about this project?

Upgrading from Oracle release 8.1.7.4 to 10g R2 is quite a project. This is an upgrade project that will require significant testing of both the actual database upgrade but, more importantly, how your applications will perform with 10g R2. I would suggest that you choose the best migration path for your database (this would depend on the size of the database, length of production outage allowed, etc.) and then perform the upgrade process several times in a non-production environment. After the database is upgraded each time, ensure that all application support teams affected by this upgrade have a chance to test their applications.

For more information, you can refer to the Oracle Database Upgrade Guide.

You will find very useful information in this guide with respect to planning a migration, as well as the actual steps that you must take to upgrade your database. The key word to remember is test, test, test!
